    • Absolutely love this serum – a skincare must-have!
Size: 1.01 Fl Oz (Pack of 1)
I’ve tried quite a few hyaluronic acid serums over the years, but this one from La Roche-Posay is easily a standout. From the very first use, my skin felt noticeably more hydrated, smooth, and plump. I love the lightweight texture—it absorbs quickly without feeling sticky or greasy, and it layers perfectly under moisturizer or makeup. The combination of Vitamin B5, hyaluronic acid, and madecassoside seems to work wonders on my skin, especially during dry or irritated days. I have sensitive skin and was happy to find this formula is gentle yet effective. No breakouts, no redness—just healthy, glowy skin. I’ve been using it daily, and I can honestly say I’ve seen a visible improvement in the texture and suppleness of my skin. If you’re looking for a high-quality, hydrating serum that delivers real results, this is it. Highly recommend! ... show more

    • smooths dry patches, calms redness, and makes foundation look flawless.
Size: 1.69 Fl Oz (Pack of 1)
My skin is dry and sensitive, with redness on both cheeks. When I wear foundation, I often get flaky skin around my nose and caking under my eyes. I’ve tried many hydrating primers, but most are too oily and end up pilling. This serum, though, is different. It’s very hydrating but feels more watery than oily, so it absorbs well and works beautifully under makeup. My foundation adheres smoothly, and the finish looks even and polished — no dry patches, no cakiness. Even when my skin is sensitive and red (yes, I know I shouldn’t be wearing makeup, but sometimes work calls for it), this serum protects and soothes my skin instead of irritating it. It’s become my go-to for both skincare and makeup prep. ... show more

I bought this 3 la roche posay set coz I want to lighten my face as am always expose cleaning our swimming pool everyday and florida weather made my skin darker. I dont use skincare coz im lazy and busy and has sensitive skin but I found this brand from my flight attendant friend coz her skin was amazing!!!and ddnt think twice to try bcoz of her! - Mela b3 - to lighten my face (day and night use) - Hyalu b5 - to hydrate my face and help with fine lines in my eyes, anti aging serum (day and night use) - Hydraphase- for dehydrated skin and dull complexion (day and night use) When I wrote this feedback its my 6th day using it and am so happy so far. No breakout, not affecting my skin, no stings, no weird side effects in my face, it feels really good in my face and my make up became awesome looking its not caky anymore and no more annoying lines from my foundation , thats when i found out my skin is normal to dry skin (i get caky and lines when im on foundation) and these set helps me a lot!!! Hoping to bring back my lighter face soon with mela b3!!! Negative part, Its little pricey but so worth it!!! ... show more

    • Smooth and Moist
Size: 1.01 Fl Oz (Pack of 1)
So far, a month in, and this product has been great. Yes, there is a smell to it but it dissipates quickly and does not bother me (I’m typically very scent sensitive). I’ve added the moisture to my routine and have been pleased. My skin is looking smoother and more hydrated.

I’m on my second bottle of the La Roche-Posay Hyalu B5 Serum and I absolutely love it! I use it every night, and it leaves my skin feeling hydrated, plump, and glowing. The hyaluronic acid in this formula is amazing, it absorbs beautifully and gives my skin that dewy, healthy look I adore. This serum has become a staple in my nighttime routine, and I’ll definitely keep ordering it. It’s gentle, effective, and makes a real difference. Highly recommend! ... show more

    • A great serum w/ impressive results
Size: 1.69 Fl Oz (Pack of 1)
I'm 54, with combination skin and I've been using the LaRoche-Posay Hyalu B5 serum for several months. It has made a noticeable difference in my skin texture and reducing the appearance of wrinkles around my eyes. I also love the subtle scent and it layers well under moisturizer and sunscreen. My husband also uses this serum every morning, which is saying a lot since its the only step in his skin care routine besides cleanser, lol. This is on subscription for us. Definitely worth adding to your regimen! ... show more
